Mercedes-Benz GLC-Class vs Genesis GV80

What's the difference?

Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.

Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.

Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.

For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.

I rarely drive luxury vehicles so it doesn’t take much to impress me. However, it’s clear to anyone with half a brain (even me) that the GV80 is a premium ride and in Black guise it’s even better, albeit by increments only and those perceived improvements largely hinge on styling tweaks to the Signature platform on which it’s based.

Does it tick all of the boxes that someone considering this type of vehicle would want ticked? Sure it does and then some. But there’s plenty of stiff competition in the form of other premium AWDs on the market nowadays and even some 4WD wagons that offer similar levels of prestige.

The GLC63 is unmistakably an AMG from the moment you first lay eyes on it. That’s thanks to the AMG-specific elements, starting with the grille with vertical strikes and the AMG crest on the bonnet; which is now a signature item for the performance sub-brand.

The GLC63 is also fitted with the Night Package II design kit; this adds a darkened grille and black chrome badging to further enhance its visual appeal.

The AMG-specific alloy wheels and more aggressive stance do mean the GLC63 stands out from the rest of the GLC range, helping it look fast even when it’s standing still.

I most frequently test and review vehicles that are tall, bulky and have plenty of ground clearance – usually 4WDs – so the GV80 is, in my experience, a mild revelation.

Firstly, it’s low and sleek and practically oozes – yes, oozes – prestige. Word of warning here. If you don’t like black as a colour on your car you’re in the wrong place because the GV80 Black and GV80 Coupe Black are only offered with – you guessed it – a black exterior and interior.

Secondly, this G80’s interior is a plush mix of quilted Nappa leather upholstery with black suede inserts, black ash wood trim, an abundance of soft-touch surfaces and very impressive all-around fit and finish. The interior of the cabin makes a strong style statement but it’s not over the top.

Genesis Motors Australia also says it has used a range of eco-friendly materials, including leather upholstery and door trims dyed using recycled carbon-black extracted from waste tyres. So, there’s that.

The cabin more than matches its rivals, such as Audi Q7, BMW X5 and Mercedes-Benz GLE, in terms of pure styling and as for practicality? Well, keep reading…

Inside the GLC63 is clearly a derivative of the rest of the range, with its C-Class-inspired design and layout, but there’s enough AMG-specific elements to ensure it looks and feels special. This starts with the AMG steering wheel, which comes not only with a thick rim wrapped in Alcantara, but also some AMG special dials to adjust the various performance settings for the powertrain, suspension and transmission.

Then there are the AMG-specific seats, which look good and offer good support for the driver and front seat passenger. The rear seats offer decent space for what is a mid-size SUV, with room enough for two adults or teenagers or three smaller kids.

Those in the back aren’t particularly well looked after though, with only rear air-con vents and small door pockets but no USB charging ports or other small item storage.

The boot is 590 litres, down from 620L in the rest of the range, thanks to the addition of the rear-mounted electric motor. There’s also no room for the temporary spare the rest of the GLC range gets and instead you have to make do with a puncture repair kit.

The GV80 Black is the same size as the standard GV80 – 4940mm long (with a 2955mm wheelbase), 1975mm wide and 1715mm high – so nothing has changed there.

And because the Black treatment is all about the looks, inside and out, the interior remains the same as standard for roominess and practicality. So, let’s dive into it.

First up, the 27.0-inch multimedia touchscreen dominates upfront, which is handy because it’s from here you operate most of the GV80’s controls. Thankfully, though, there are some physical dials and buttons, as well.

That screen is big, the colours are clear and crisp and the on-screen controls are easy to use, even for a true luddite like me.

Same goes for the driver display and the 12-inch head-up display. Clear to read and versatile enough in configuration choices to set them up as you want.

Then, everything flows on from that well-appointed dash.

The steering wheel is heated and power adjustable. By the way, I still don’t see why a heated steering wheel is a thing in Australia. Nowhere on this continent is cold enough to warrant it.

All seats are soft but supportive and very comfortable as you’d expect in a prestige vehicle with an interior that’s replete with “rich textures and bespoke materials”, according to Genesis.

There’s adequate seating room all-around, but the third row is squeezy and best suited to children or other height-challenged people that you despise.

The front seats are 18-way power-adjustable, heated and ventilated. They even have a massage function – if that’s your particular cup of tea.

The second row has heated and ventilated outboard seats (with power-base tilt and backrest recline), and there’s a climate-control panel each for the second and third rows.

Charge points abound with USB and 12V options available in the front and second row.

There are plenty of storage options throughout the cabin including a glove box, sunglasses case, cupholders etc. But the door pockets are narrow and awkward to get anything in and out of. A minor annoyance, but an annoyance, nonetheless.

In terms of cargo area capacity, with all three rows up and in use there is a claimed 327 litres of space available, 727L with the power-folding third row stowed away, and 2147L with the second and third rows folded down and out of the way.

Worth noting for anyone who drives beyond city limits is the fact this vehicle does not have a spare wheel, it only has a tyre mobility kit attached by Velcro to the rear cargo area floor.

The GV80 also has a power-operated tailgate.

The top-spec GV80 Black variants are based on the GV80 Signature 3.5T-GDi AWD and are only offered with that powertrain.

Our test vehicle, the seven-seat GV80 3.5T Black all-wheel drive SUV, has a Manufacturer’s List Price (MLP) of $136,250, while the five-seat GV80 Coupe 3.5T Black AWD has a MLP of $141,750. Both prices exclude on-road costs but include Luxury Car Tax where applicable.

Standard features onboard this test vehicle include:

• 27.0-inch OLED integrated multi-media touchscreen
• Wireless Apple CarPlay and Android Auto
• Built-in satellite navigation
• 18-speaker Bang & Olufsen audio
• 12.0-inch head-up display
• 18-way power-adjustable heated/ventilated/massage front seats
• Heated centre console
• Heated and ventilated second-row outboard seats (with power-base tilt and backrest recline)
• Second-row climate control panel
• Separate second- and third-row temperature control
• Power-operated tailgate
• Mood Curator (which is incidentally what I call the axe handle I keep by my bed for household protection)

Other features that set this Black variant apart from its stablemates include interior highlights such as a dark-tinted Genesis steering wheel logo, quilted Nappa leather upholstery (with black suede accents), welcome and goodbye animations, black ash real wood trim, black garnishes, bezels and switchgear and black aluminium speaker grilles.

Exterior highlights include black 22-inch wheels and brake calipers, black G-Matrix grille, dark-tinted Genesis front emblem and tailgate lettering and black body cladding.

All 2026 GV80s also get what Genesis calls a “Digital Key 2.0”, which enables users to lock and unlock front and rear doors and start the engine using a smart-phone or -watch. It can be stored on one device and shared with up to 15 devices.

Black is the exterior paint colour. Matt paint is optional and costs $2000.

This is what lies at the heart of the AMG GLC63’s success or failure. As I mentioned at the beginning, the previous generation’s 4.0-litre twin-turbo V8 has been replaced by an F1-inspired plug-in hybrid powertrain.

But don’t think that means AMG is suddenly focused on efficiency over performance. When AMG says the powertrain is inspired by the brand’s success in Formula 1 racing, what it means is the battery and electric motor provides a significant performance boost to support the internal combustion engine, not just save fuel.

To that end the combination of the turbocharged 2.0-litre four-cylinder petrol engine and the rear-mounted electric motor produces an impressive 500kW and 1020Nm. That’s a massive jump over the 375kW/700Nm made by the outgoing V8.

This Genesis GV80 Black has a 3.5-litre twin-turbocharged V6 petrol engine producing 279kW and 530Nm, matched to an eight-speed automatic transmission.

This SUV has an all-wheel drive system and an electronic limited-slip rear differential.

The GV80’s engine has plenty of punch and the auto is impressively cluey as well.

Mercedes makes no secret that the battery is designed for performance, not saving fuel. It only has a 14km EV range but can recharge quickly on the move to provide a power boost when needed.

But despite all that, the GLC63 is actually significantly more fuel efficient than the old V8, using a claimed 7.3L/100km, which is a massive 4.9L/100km improvement over the old model. Although, on our day-long test drive we didn’t manage to come close to that claimed figure and instead saw returns around 11L/100km, albeit after a lot of spirited open-road driving.

Official combined cycle (urban/extra-urban) fuel consumption is listed as 11.7L/100km.

On test we were seeing a dash-indicated 9.6-9.8L/100km but recorded an overall average of 12.4L/100km after a mix of city, highway and suburban driving.

The GV80 has a 80-litre fuel tank so, going by our on-test fuel figures, you can reasonably expect a driving range of about 645km from a full-tank.

Worth noting this car requires 95 RON premium fuel.

Anyone who still believes in the adage ‘there’s no replacement for displacement’ hasn’t driven a modern turbocharged and hybridised engine. The GLC63 is a demonstration of the metaphorical and literal power of modern technology, combining an extremely efficient and potent internal combustion engine with an electric motor to make enormous real-world performance.

To be blunt, the GLC63 feels like a rocketship out of corners, launching with a ferocity and relentlessness the old V8 simply can’t match. It shouldn’t come as a surprise, a mid-size SUV with 1020Nm was always going to have plenty of performance, but even so it’s a shock to the system every time you give the GLC63 full throttle. Officially AMG claims it takes just 3.5 seconds to run 0-100km/h and has an electronically limited top speed of 275km/h - mighty impressive figures for a five-seat mid-size SUV.

To help get all that torque to the road, AMG deploys torque distribution technology that allows for it to be split an even 50/50 front/rear all the way to 100 per cent to the rear tyres.

Other technologies deployed to enhance its handling include AMG Ride Control suspension with adaptive damping and rear-axle steering. There’s also eight AMG Dynamic Select driving modes and four AMG Dynamics settings (Basic, Advanced, Pro and Master), so it’s a complex vehicle that is designed for the enthusiast.

While it’s easy to drive around town, once you get out on the open road you can really get a sense of the GLC63’s performance potential. Beyond just its powertrain the suspension offers good body control and the rear-axle steering helps it feel agile and responsive. 

It’s not perfect though. At times the complexity of the system does lead to some hesitation when you put your foot down. It certainly lacks the linear power delivery of the old V8 and makes for a slightly trickier driving experience at times.

As for the sound, which is one of the biggest elements missing from the V8, Mercedes has added AMG Real Performance Sound, which features a pressure sensor in the exhaust that picks up on the engine note and plays it through the speaker system. It certainly helps make for a louder, more noticeable engine noise, but it still sounds more like an A45 than the previous GLC63 and for many would-be buyers, that’s a major turn-off.

An excerpt from my initial drive notes on the GV80 Black read "smooth, slick (too slick?), impressive open-road cruising, plush, couch on wheels”. All sound points but there’s even more to this car.

For a big wagon, the circa-2345kg GV80 gets off the mark nicely with a crisp throttle response and it punches along at a fair clip once on the move. There’s little to no noise from the outside world, other than the low-key rumble of the V6 and it’s easy to hit the speed limit without realising.

The power-adjustable steering wheel can be dialled in for a preferred position and while this weighty AWD still exhibits minor body roll through tighter corners that characteristic can be restrained somewhat via the Sport drive mode for better suited suspension behaviour and controlled with sufficiently precise steering.

Ride and handling are well sorted out with the GV80’s all-wheel drive system and an electronic limited-slip rear differential giving the driver welcome levels of confidence in a variety of driving conditions.

Turning circle is listed as 11.98m and this car doesn’t feel unwieldy on busy suburban streets.

A few niggles. Digital rear-view mirrors are not among my favourite features in cars as they offer a headache-inducing fish-eye view of the world not to my liking and such is the case in this GV80.

Speaking of views, because the GV80 is low and sleek, it doesn’t afford the driver the levels of visibility I’m used to getting in the taller, more upright vehicles I most frequently review.

All-around, however, the GV80 is a smooth daily driver, with plenty to like about it and just a few foibles.

The Genesis GV80 3.5T Black does not have an ANCAP safety rating because it has not been tested.

As standard it has 10 airbags (including side curtain airbags) and driver-assist tech includes forward collision-avoidance assist, lane keep assist, highway driving assist, smart cruise control, a surround-view monitor and more.

The second row has ISOFIX child-seat anchors in the two outboard seats, and three top-tether points.

The GLC63 is covered by Mercedes Australia’s usual five-year/unlimited kilometres warranty.

As for maintenance, Mercedes offers service plans, spanning three to five years. Three years will cost you $5025, $6455 for four years and five years is priced from $7180. Servicing intervals are 12 months or 20,000km, whichever comes first.

Every new 2026 GV80 is covered by a five-year/unlimited km warranty and five years' roadside assistance. If the car's serviced at an authorised Genesis dealer this coverage increases to 10 years.

Servicing, scheduled for every 12 months or 15,000km, is free for the first five years or 75,000 km, whichever occurs soonest. Genesis offers a concierge and courtesy vehicle service for five years with the complimentary service.

There are 11 Genesis dealers in Australia - Five in Sydney (including a CBD 'studio'), two in Melbourne and one each in Brisbane, The Gold Coast, Adelaide and Perth.
